Description

[Detailed Description of the Invention] The present invention relates to a fertilizer supply device for a riding rice transplanter equipped with a fertilization device, and is configured to smoothly supply fertilizer from a fertilizer tank to a fertilizer embedding device.

By the way, rice transplanters are equipped with a fertilization device to perform fertilization work at the same time as planting seedlings. In this case, the fertilizer tank in the fertilization device is attached to the machine body, and the fertilizer embedding device in the device is attached to the planting machine, so the fertilizer supply hose that connects the fertilizer dispensing part at the bottom of the tank and the embedding device is long. This causes problems such as clogging of the fertilizer inside the hose.

The present invention addresses the above-mentioned problems in the fertilization device of a riding rice transplanter, and consists of a fertilizer tank attached to the traveling machine, a fertilizer embedding device attached to the planting machine, and a fertilizer embedding device attached to the bottom of the tank. In a configuration in which the provided fertilizer feeding section and the embedding device are connected via a hose, a spiral groove is formed on the inner surface of the hose connecting tube at the outlet of the feeding section, and air is forced into the connecting tube from the outside. By merging the inflow pipes such as the above, a swirling flow of air, etc. is formed in the connecting pipe or the hose connected to this, and this prevents the fertilizer supplied from the tank to the embedding device from clogging the hose. This allows the water to flow down smoothly without any problems.

Hereinafter, the present invention will be explained based on an embodiment. In Figs. 1 and 2, 1 is a traveling body of a riding rice transplanter, and a pair of left and right front wheels 2 and rear wheels 3 are used as a traveling device.
The upper part of the aircraft is a control section equipped with a seat 4, a handle 5, various levers 6, etc.
Moreover, an engine 7 is mounted on the front part of the aircraft. Reference numeral 8 denotes a planting machine connected to the rear part of the machine body 1 via a parallel link mechanism 9, and includes a hydraulic cylinder 10.
The work machine can be lifted upward from the planting position shown in the figure through the link mechanism, and the work machine is equipped with a seedling stand 11, a planting claw 12, etc. A float 13 is provided to hold it above the surface. 14 is a fertilizer application device;
This device is composed of a fertilizer tank 15, a fertilizer embedding device 16, and a fertilizer supply hose 18 that connects the fertilizer feeding section 17 at the bottom of the tank with the embedding device. , the embedder 16 is the planting machine 8
It is attached to the front part of the float 13 via an attachment member 19. However, as shown in FIGS. 3 and 4, a spiral groove 20a is formed on the inner surface of the connecting pipe 20 of the hose 18 at the outlet of the feeding portion 17, and a spiral groove 20a is formed in the connecting pipe. Air inflow pipes 22 led from an engine cooling air collector 21 installed at the rear are joined together. According to the above configuration, the fertilizer stored in the fertilizer tank 15 during the planting operation is supplied to the fertilizer embedding device 16 through the feeding section 17 and the hose 18, so that the fertilizer is delivered to the field at the same time as the seedling planting operation. In this case, the engine cooling air generated by the cooling fan 7a of the engine 7 passes through the air collector 21 and the inflow pipe 22 to the hose connection pipe 2 in the feeding section 17.
Since the spiral groove 20a is formed on the inner surface of the connecting pipe, a swirling flow of air is formed within the pipe and the hose 18 connected thereto. The fertilizer supplied from the tank 15 to the embedder 16 can be smoothly and reliably flowed down without clogging the hose. Here, as shown in FIG. 4, the inlet pipe 2 is connected to the connecting pipe 20.
2 in the connecting direction, combined with the effect of the spiral groove, a stronger swirling flow can be obtained within the connecting pipe or hose.

In the embodiment of the switch, the fertilizer tank 15 is installed on both sides of the aircraft body 1 below the seat 4 as shown in FIGS. 1 and 2, but as shown in FIG. 3', 3', or the tank 15'' may be installed on the back of the seat 4'' as shown in FIG. All you have to do is install a tank. In addition, the air flowing into the connecting pipe 20 or the hose 18 is not limited to the engine cooling air in the above embodiment, but air flow generated by a separately installed pump, or exhaust gas discharged from the engine may be used. It is also possible to use

As described above, the present invention provides a riding-type fertilizing rice transplanter in which a fertilizer tank is attached to the traveling machine side and a fertilizer embedding device is attached to the planting machine side, and the inner surface of the hose connecting pipe in the fertilizer delivery part at the bottom of the tank is Since a spiral groove is formed and an inflow pipe for air, etc., which is pumped by an appropriate means is joined to the connecting pipe, a swirling flow is formed in the connecting pipe or the fertilizer supply hose connected thereto. As a result, fertilizer can be smoothly and reliably supplied from the tank to the embedding device, and clogging of the fertilizer in the hose can be prevented.
